I'm guessing that, you might have made that purchase by now? The .17 Hornet started life as a wildcat, meaning that you had to make it from .22 Hornet brass using several forming dies that swaged the brass down. More recently, it's become a factory cartridge. So just be careful that the barrel you use is the same spec as the ammo you use as I think there's some small but important differences. If it's a new barrel, it'll probably be set up for the new ammo and visa-versa.
The .17 Hornet has a couple of advantages. The recoil is so mild that you can usually see the impact of the bullet because the scope stays on the target. Also, the bullet is much less likely to glance off something, instead going into pieces, so it's relatively safer in more settled areas. Lastly, it's less likely to exit critters of fox size which is great if you want their pelts.
On the down side, if you reload, it's not as easy to handle little components. You'll also need .17" size cleaning rods and funnels. However all Hornet cased ammo is cheap to load and that pound of powder you buy for it will last you some time. So good luck with it. posting.php?mode=reply&f=85&t=199130&sid=77f6a40f321b4d5c910e09126c28917b#
